A local layout.

Arcspan's calculator processes entered dimensions and station counts in your browser. It does not submit measurements or generated results to an application server.

Inputs and exported layouts

The calculator does not append inputs to request URLs, use an account, or save values in cookies, localStorage or sessionStorage. Current entries can be lost on restore, reload or closing the page. The browser may separately remember form values under its own settings. SVG and CSV files are generated locally, and Copy uses your browser's clipboard with a selectable-field fallback. You control where downloads are saved or shared.

Cloudflare Web Analytics

Cloudflare Web Analytics is enabled in this site's hosting settings. Cloudflare Pages adds its measurement beacon on deployment. When that beacon loads, it collects page-view and page-performance information for aggregate website reports. Blocked scripts or failed beacon requests can prevent measurement, so reports may be incomplete.

The calculator's own code does not attach the measurements you enter or its results to analytics events. Visits and page views are not counts of unique people or proof of organic search traffic. Hosting and security requests are separate from these reports; this notice does not claim that infrastructure providers keep no logs. Read Cloudflare's Web Analytics explanation and Cloudflare's privacy policy.

Advertising

Publisher metadata and ads.txt identify the intended Google publisher account. They do not deliver advertisements or establish approval or earnings. No advertising delivery or consent-message script is active in this release. Advertising and consent settings from another website do not automatically apply to this host; its notice must reflect any later service configuration.

Email correspondence

The public address yardfill.helpful594@aleeas.com is the verified existing shared Yardfill forwarding alias, reused for Arcspan. Messages pass through SimpleLogin to the owner's mailbox; no separate Arcspan mailbox has been created. If you email, those providers and the owner receive the sender address, message and associated metadata. Include only the details needed for the enquiry, without account credentials or sensitive project information.

Questions and changes

Use the shared contact inbox for privacy questions or a request about an email you sent. External reference sites and export-viewing software have their own practices. This notice describes the prepared source release and needs review when hosting or external services change. No contact is required to use the calculator.
